ThreadGate::Counter Class Reference

#include <coherence/util/ThreadGate.hpp>

Inherits Object.

List of all members.

Detailed Description

Counter is a mutable integer class.

Public Types

typedef spec::Handle  Handle
  Counter Handle definition.
typedef spec::View  View
  Counter View definition.
typedef spec::Holder  Holder
  Counter Holder definition.

Public Member Functions

virtual int32_t  getCount () const
  Return the count.
virtual void  setCount (int32_t c)
  Set the count.
virtual int32_t  increment ()
  Increment the count by 1.
virtual int32_t  decrement ()
  Decrement the count.
virtual void  toStream (std::ostream &out) const
  Output a human-readable description of this Object to the given stream.

coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toStream method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents.

 Object::View vKey   = ...
 Object::View vValue = ...
 std::cout << vKey << " = " << vValue << std::endl;

 String::Handle hs = COH_TO_STRING(vKey << " = " << vValue);
out  the stream used to output the description
